Climb down entrance slope to a crawl which leads to the first pitch of 21m with Y-hang rebelays at -3 and -7m. This is followed by a pitch of 4.3m and finally a tight and loose pitch of 14.6m (rebelay needed) to a boulder choke and aven.

A mud and water duck may respond to digging as there is a slight draught.
